COMBUSTION PROMOTING DEVICE Filed Sept. 13, 1929 l nt-rented 'May 31, 1%??? UNITED STATES ears T DFFICE COMBUSTION PEOMQTING DEE 16E Application file'd September 13, 1829.

his invention relates to a conzhustion pro- .r.-oting device for internal combustion engines the general object of the invention being to provide means for securing more miles per gallon of fuel, preventing overheating of the parts of the engine and decreasing the dilution of the oil in the crank case, practically eliminating the formation of carbon in the cylinders, reducing the amount of carbon monoxide in the exhaust and. otherwise increasing the etficiency of the engine.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to he hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, rel? erence Will he had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the set" views, and in which Figure 1 is an elevation showing the in vention in use on an engine.

Figure 2 is a top plan'vievv of the device;

Figure 4 is a bottom plan vievs of the rotor,

in those vies-n the numeral 1 indicates a substantially spherical. shaped casing having upper and lower ends open with through the flanges of the carburetor and old. The upper and lower internal is the device are of cylindrical form, the lower end of the upper wall extend- 1" lg into the spherical-shaped body to provide an annular flange 4 which has an upwardly and outwardly sloping outer wall vvfieh merges into the upper end of the internal. Wall the hody so as to leave an annular groove at this point. A spider 'E" is located Ito, 332,406.

within the body at a point slightly above the center thereof and its central parthas an opening therein to receive the upper end of ashaft which threaded to receive a nut 9 which holds the shaft in the spider. A ortion of the upper end of the shaft is also threaded to a part of the spider. A rotor 10 is rotatably supported on the shaft and antifriction nwnihers ll are provided for reducing friction. tion with its large end uppermost and its sides curving'inwardly, as shown at 12.

A plurality of blades 13 is formed on the rotor, each blade gradually increasing in h from the lower end of the body to a point adj scent the upper end thereof and this upper end straight and vertical, as shown at 13. The blades are tangentially arranged on the rotor in. the usual manner so that the rotor will he revolved as the explosive mixasse through the body from the carintake manifold.

is formed with a tangential port c located that the vapors passing into the port "will impinge the blades of the rotor. A pipe 15 connects this port with the breather 15 of the crank case, the pipe having a loose fit in said breather and a branch. pipe 16 connects the pipe 15 with the top part of the radiator of the motor so that the vapors from the radiator and the crank case will be drawn into the device by ie piston suction of the engine when the valve 17 in the pipe 15, is

From the foregoing it will be seen that the stream of explosive mixture drawn from the carhureter into the engine cylinders by the on suction will strike the rotor and thus cause the same to rotate at a high speed and the piston suction will also draw vapors from the crank case and radiator into the device. are thoroughly mixed together by the revolving rotor and the centrifugal action will throw the heavy particles against the Walls 'lhe vapors and explosive mixture The rotor is of tapered forma- Hr; no

of the body, while the thoroughly mixed vaporized portions of the mixture will pass through the device into the manifold. The heavier portions thrown against the walls of the body will move up the walls thereof into the groove 6 and as the bafiie 4 prevents such portions from entering the manifold, such portions that are not vaporized will drop from the bafile or flange and be again acted on by the rotor.

Thus the mixture, including the mixture of fuel and air from the carbureter and the vapors from the crank case and radiator, will be thoroughly mixed before it enters the cylinders and practically all the unvaporized portions will be prevented from entering the cylinders and as the mixture is thrown against the walls of the device by the rotor, the mixture enters the cylinders in a cool condition, thus preventing overheating of the parts of the engine.

As before stated, this invention will increase the efiiciency of the engine, greatly reduces the consumption of fuel, prevents crank case dilution, thus keeping the oil pure and eliminating frequent changing of oil, greatly reducing formation of carbon, reduces carbon monoxide in the exhaust and otherwise "1; cases the eaiciency of the ens in the foregoing description the advantages and novel features of the invention will be readily apparent.

lit is to be understood that changes may be made in construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims l/Vhat claim is l. 1 device of the class described comprising a substantially spherical-shaped body having its upper and lower ends open, means for connecting the upper end, of the device with a manifold of an internal combustion engine and its lower end with the carbureter of the engine and a rotor in the body of substantially frusto-conical shape with its large end uppermost and having blades on its e1:- terior surface whereby the passage of the combustible mixture through the device will rotate the rotor and said rotor will, through the action of centrifugal force, cause the mixture to be thrown against the walls'of the body, each blade gradually increasing in width from the lower end of the rotor to a point adjacent the upper end thereof, with the top of the blade straight and vertical.
